The ARM® Cortex®-R family is perhaps the unsung hero of the ARM powered world, quietly running infrastructure from Hard Disk Drive and Solid State Drive controllers, through to mobile phone baseband processing and even automotive ABS controllers. While not having the all-out performance of the Cortex-A series application processors, the Cortex-R family of processors provide several key benefits for systems requiring hard, real-time performance.
The main differences between application processors and real-time processors are:
The new ARM Cortex-R Series Programmer’s Guide extends the software development series of programming guides available from ARM by covering Cortex-R series processors conforming to the ARMv7-R architecture.
The Cortex-R Series Programmer’s Guide describes the following areas which differ between the Cortex-R series and the Cortex-A and Cortex-M series:
This guide is aimed at anyone writing software for the Cortex-R family of processors, and complements, rather than replaces the existing documentation for the Cortex-R family.
If you’re new to using Cortex-R processors and looking to understand where to begin writing bare-metal programs, or you’re an experienced applications designer wanting to understand how to make the most of the underlying processor, then this guide is a good introduction to the Cortex-R family.
The document is only available to registered ARM customers. See, Cortex-R Series Programmer's Guide.
Hello Qamarina, thank you for taking the time to tell us about the issue you are meeting.
May you please tell us which browser (type + version) and operating system you are using?
Also, have you tried without browser extensions or in Incognito or Private browsing mode? There might be a browser extension involved and I would like to try and reproduce the issue here and with your information, I will ask ARM IT team to have a look.
Hi Jim, thanks for the link, it is nice and clear! ARM corporate site captcha is much easier to read than it used to be...
